Hi,
I need to synchronize some tables from a database (master) to another
one (slave).
Both servers are running Debian Woody with PostgreSQL 7.2.1 (postgresql
7.2.1-2woody4).
The databases are in unicode and doesn't contain any binary data.
The tables have primary/foreign key constraints, sequences and indexes,
but no triggers/rules. There are OIDs but these are different on the 2
databases. In fact they are not used by the application.
I need to do that ASAP, and hopefully only once (there are already some
kind of home-made replication scripts, that are not the origin of my
problem).
Later I would like to set up pgreplication or something... any advice on
that is welcomed too ;-)
What would be the fastest way to achieve that?
On the master:
For each table, use COPY TO or pg_dump?
On the slave:
- delete everything from these tables
- drop the FK constraints
- (drop indexes?)
- vacuum (or later?)
- import from files (using COPY FROM or pg_restore)
- recreate the FK constraints
- update the sequences
- reindex (or recreate them)
Does that sound good?
Thanks for you help,
